The plan of the fort is irregular and probably the biggest in the sub-continent. The fort has been divided into two main zones, the north-west quadrant, separated from the rest fort by an inner wall, called Andarkot and was probably reserved for the accommodation of the high officials. The extent of the perimeter wall, including the subsidiary fortification wall dividing the fort into two main parts is about 5.6 km. It contains 68 semicircular bastions and 12 gateways. The inner citadel has three of the four intact structures of fort, the so-called Raja Man Singh Haveli, the Shahi Masjid and one of the two baolis inside the fort.
